Heat-dissipation structure

Abstract

A heat dissipation structure including a wind cover, a heat sink and a wind-shielding plate is provided. The wind cover has an outlet and a fan connection portion corresponding to the outlet and having an inlet. In addition, the heat sink includes a base, multiple fins disposed in the wind cover, and at least a heat pipe passing through the fins and being fixed on the base. The wind-shielding plate is connected to a lowest one of the fins for leading an air flow to move around a heat source. Accordingly, the waste heat near the heat source can be taken away.

1 . A heat-dissipation structure, comprising: 
 a wind cover, having an outlet and a fan connection portion corresponding to the outlet, the fan connection portion having an inlet;    a heat sink, comprising a base, a plurality of fins disposed in the wind cover, and at least a heat pipe passing through said plurality of fins and being fixed on the base; and    a wind-shielding plate, connected to a lowest one of said plurality of fins.    
   
   
       2 . The heat-dissipation structure of  claim 1 , wherein at least one vertical side plate with at least one ventilator is disposed at a bottom of the wind cover.  
   
   
       3 . The heat-dissipation structure of  claim 1 , wherein at least one side plate is disposed at the bottom of the wind cover, the side plate having a bent edge being in a tilting angle and having at least one ventilator.  
   
   
       4 . The heat-dissipation structure of  claim 1 , wherein the heat sink further comprises a fixing plate connected to the heat pipe and the base respectively.  
   
   
       5 . The heat-dissipation structure of  claim 4 , wherein the fixing plate is connected to the heat pipe and the base by welding.  
   
   
       6 . The heat-dissipation structure of  claim 1 , wherein the wind-shielding plate is connected to the lowest one of said plurality of fins by welding.  
   
   
       7 . The heat-dissipation structure of  claim 1 , wherein the wind-shielding plate is a vertically bent portion of the lowest one of said plurality of fins.  
   
   
       8 . The heat-dissipation structure of  claim 1 , further comprising a fan disposed on the fan connection portion.  
   
   
       9 . A heat-dissipation structure, comprising: 
 a wind cover, having an outlet and a fan connection portion corresponding to the outlet and having an inlet;    a heat sink, comprising a base, a plurality of fins disposed in the wind cover, and at least a heat pipe passing through said plurality of fins and being fixed on the base; and    a wind-shielding plate, connected to both sides of the wind cover.    
   
   
       10 . The heat-dissipation structure of  claim 9 , wherein at least one vertical side plate with at least one ventilator is disposed at a bottom of the wind cover.  
   
   
       11 . The heat-dissipation structure of  claim 9 , wherein at least one side plate is disposed at the bottom of the wind cover, the side plate having a bent edge being in a tilting angle and having at least one ventilator.  
   
   
       12 . The heat-dissipation structure of  claim 9 , wherein the heat sink further comprises a fixing plate connected to the heat pipe and the base respectively.  
   
   
       13 . The heat-dissipation structure of  claim 12 , wherein the fixing plate is connected to the heat pipe and the base by welding.  
   
   
       14 . The heat-dissipation structure of  claim 9 , wherein the wind-shielding plate is connected to both sides of the wind cover by welding.  
   
   
       15 . The heat-dissipation structure of  claim 9 , wherein the wind-shielding plate and the wind cover are integrally formed.  
   
   
       16 . The heat-dissipation structure of  claim 9 , further comprising a fan disposed on the fan connection portion.
